Chapter 17, Problem 2RQ
Summary Introduction
To review:
The types of evidences that support the existence of life in the Archaean eon with their advantages and limitations.
Introduction:
Archaean Eon is regarded to be the earliest one of the two divisions of Precambrian time (this lasted from 4.6 billion to 541 million years ago) and the period when life first arose on Earth. The beginning of this Eon is marked with the formation of Earth’s crust and it extends to the beginning of the Proterozoic Eon.

Why are archaebacteria called living fossils?
Isoprene serves as a building block not only for the hydrocarbons observed in archaeal membranes but also for sterols, carotenoids, retinal, and quinones. Use any resources necessary to identify the function of these other isoprene-based molecules and to determine their distribution in nature. What does the use of isoprene to make this diverse array of molecules suggest about the nature of the last universal common ancestor (LUCA)?
An organism dies,and its body leaves an impression in mud. Over time, the mud hardens into rock, and the impression becomes a fossil. Which kind of fossil was formed?
A) cast
B) mold
C) original material
D) trace fossil

- The TATA-binding protein (TBP) is thought to be necessary for transcription in all eukaryotic cell nuclei. Studies show that archaea, but not bacteria,have a protein structurally and functionally similar to TBP. What does this similarity suggest regarding the evolution of archaea, bacteria, and eukaryotes? How might knowledge of this similarity affect how systematists classify these organisms?arrow_forwardState in what ways Stanley miller simulated the condition of :-i) Primitive atmosphere on earth.ii) Energy source at the time of origin of life .iii) Formation of organic molecule of life.arrow_forwardHere is the question: What was the likely source of the raw material incorporated into the first life forms? I believe it is carbon, but I don't know why it is carbon. What I mean is, why is carbon considered the thing that makes something alive? Why are eukaryotes and prokaryotes simply considered alive just because they have carbon. Would that mean that carbon is alive because carbon has carbon? I would appreciate an anwser because I'm really trying to understand everything I run across. I love educating myself and I'm on a quest for knowledge. Thanks guys!arrow_forward
